【 摘 要 】

Optical effects arising from spin-induced gain anisotropy such as threshold reduction and emission intensity enhancement, hitherto unobserved in electrically injected polariton lasers, are predicted theoretically for a bulk GaN-based exciton-polariton diode laser operated with electrical injection of spin-polarized electrons. These phenomena are deduced from a simplified spin-dependent rate equation model. We also demonstrate an electrical excitation scheme, which can amplify the degree of a deterministic circular polarization of the output emission by an order of magnitude, compared to the injected electron spin polarization, above threshold.
